Description
Cette macro crée un triangle isocèle en donnant comme argument , l'angle de tête et la hauteur du triangle. La tête du triangle est positionnée aux coordonnées XYZ 0,0,0.
Use
Copy the macro Triangle AH complete in the Python console FreeCAD and type:
triangleAH(angle=90, height=10)
# or
triangleAH(90, 10)
# or
triangleAH(45, hypo=10)
# or
triangleAH(90, base=10)
